4.1.2 Sensor analog output channels
The firmware supports two independently-configurable analog output channels (AO1 and
AO2). For conventional operation, the analog output channels provide identical but separate
configuration parameters including, but not limited to, the currently available AO1
configuration parameters (for content and scaling configuration). These configuration
parameters follow the same naming convention as the AO1related configuration parameters
(which retain their current names). The Boolean data point,
Analog Output 1 (AO1). NOTE: HART communication is available over AO1 only.

Each analog output has individually configurable alarm selections. The selections include:
• Very Low (3.5 mA)
• Low (4.0 mA), High (20 mA)
• Very High (20.5 mA)
• Hold Last Value
• None
Trim the analog outputs via, serial or Ethernet interfaces. The AOXActionUponInvalidContent
data point specifies the action for Analog Output 1 current when the content is invalid. No
special action is taken when set to none.
Each analog output is considered saturated if the "pre-trimmed" value is (strictly) outside the
range (3.5, 20.5) mA. Note that a value less than 4 mA should only occur if the output is invalid
and the invalid content is selected to be represented by a fixed 3.5 mA output. The database
point AOXIsSaturated shall be used to indicate the saturation status.
For each analog output, after the saturation determination is made, then the DAC -limits of (3.5,
21) mA is applied to the pre-trimmed value. The resulting value is written to the appropriate
AOXOutput database point (so that the point's meaning is consistent with the pre-HART
firmware).
The analog output trim zero and gain values (stored in database points AOXCurrentTrimZero
and AOXCurrentTrimGain, respectively) are always applied to the analog output's pre-trimmed,
DAC -limited value (i.e., the value stored in the database point AOXOutput) as shown in
Equation 1 (all values in milliamps except the dimensionless gain). The DAC - limits (3.5, 21 mA)
is applied to the resultant trim value (AOXTRIM) and DAC -limited result shall be stored in the
database point AOXOutputTrimmed and output to the DAC.

Classification:
Device variable 0 - uncorrected flow rate
The flow-condition volumetric flow rate is the result of applying expansion correction and flowprofile correction to the raw volumetric flow rate derived as shown in Equation C -1 subject to
the low-flow cut-off (see Annex C). If the resulting value is below the low-flow cut-off value, it is set
to zero. The low-flow cut-off volumetric flow rate (QCutOff) is the specified low-flow velocity
threshold (ZeroCut) converted to a volumetric flow rate.

5.2 Device variable 1 - corrected flow rate
The base-condition volumetric flow rate (QBase) is the result converting the flow-condition
volumetric flow rate to the base pressure-temperature condition. This conversion requires (1)
AGA8 calculations to be either performed internally (i.e., by the meter) or externally (with the
resulting compressibilities specified to the meter via the SpecZFlow and SpecZBase data points),
and (2) the flow-condition temperature and pressure to be live or fixed. If AGA8 calculations are
not performed (i.e., neither internally nor externally) or the flow-condition temperature and/or
pressure are/is not enabled, then the base-condition volumetric flow rate is set to zero. The
base-condition volumetric flow rate is calculated as shown in Equation C -2 (see Annex C).

5.3 Device variable 2 - average flow velocity
The meter uses two calibration steps: “dry” calibration and “wet” calibration.
The dry-calibration gas flow velocity is the result of applying a third-order polynomial equation
to the average weighted gas flow velocity as shown in Equation C -3 (see Annex C).
Note that the meter provides two sets of dry calibration coefficients - one set for each flow
direction.

Unit Codes
Average Flow Velocity
(Table 11- 8)
The Rosemount Ultrasonic meter offers three selections for wet calibration: 12-point piecewise linearization, a third-order polynomial, or none. The wet calibration method to use is
selected via the CalMethod data point with “None” being the default value. The wet
calibration gas flow velocity is calculated from the dry calibration gas flow velocity as shown in
Equation C -4 (see Annex C).
5.3.2 Piece-wise linearization
If the 12-point piece-wise linearization (PWL) wet calibration method is selected, then the drycalibration gas flow velocity is calculated as shown in Equation C -5 (see Annex C).
The inputs to the 12-point piece-wise linearization are the (up to) 12 pairs of volumetric flow
rate and meter factor for each flow direction ([FwdFlwRt1, FwdMtrFctr1], ...,
[FwdFlwRt12, FwdMtrFctr12] for forward flow; [RevFlwRt1, RevMtrFctr1], ...,
[RevFlwRt12, RevMtrFctr12] for reverse flow).
The linear meter factor is determined by the PWL inputs, the flow direction, and the drycalibration gas flow velocity.
5.3.3 Third-order polynomial
If the third-order polynomial wet calibration method is selected, then the wet-calibration gas
flow velocity is calculated as shown in Equation C -3 (see Annex C).
Note that the meter provides two sets of wet calibration polynomial coefficients - one set for
each flow direction.
5.3.4 No wet calibration
If no wet calibration is selected, then the wet calibration gas flow velocity is equal to the dry
calibration gas flow velocity (see Annex C).

5.5 Device variable 4 - energy rate
When the frequency output pair represents the energy rate (selected via the FreqXContent data
point), then the full-scale energy rate is specified via the AO1FullScaleEnergyRate data point (if
primary variable) or AO2FullScaleEnergyRate (if secondary variable). This is the energy rate that
corresponds to the selected maximum frequency and determines the frequency output pair’s
“energy K-Factor” value (readable via the FreqXEnergyKFactor data point). The minimum
frequency output (0 Hz) corresponds to zero energy rate.
When the analog output represents the energy rate selected via the AO1Content data point (if
primary variable) or AO2Content data point (if secondary variable), then the full-scale energy
rate is specified via the AO1FullScaleEnergyRate data point or AO2FullScaleEnergyRate data point (if
secondary variable). This is the energy rate that corresponds to the maximum output (20 mA).
The minimum output (4 mA) corresponds to zero energy rate. The analog output is forced to
3.5 mA when the energy rate is invalid.

5.6 Device variable 5 - mass rate
The meter calculates the mass rate and mass totals (forward and reverse). These calculations
requires that the flow-condition pressure and temperature are available (either fixed or optional
analog inputs, the gas composition is available (either fixed or optionally read from a GC), and
the AGA8 calculations are performed (internally by the meter or externally with the results
written to the meter). The mass rate is calculated as shown in Equation C -8 (see Annex C).
The sign of the mass rate indicates the flow direction: a positive value indicates flow in the
forward direction, a negative value indicates flow in the reverse direction.
When the analog output represents the mass rate (selected via the AO1Content data point), then
the full-scale mass rate is specified via the AO1FullScaleMassRate data point or AO2FullScaleMass-
Rate data point (if secondary variable). This is the mass rate that corresponds to the maximum
output (20 mA). The minimum output (4 mA) corresponds to zero energy rate. The analog
output is forced to 3.5 mA when the energy rate is invalid.

5.7 Device variable 6 - pressure
The Rosemount Liquid Ultrasonic Flow Meter samples the input analog signal(s) and updates
the corresponding data point (LiveFlowPressure) once per second regardless of the input

Every five seconds, the meter updates the “in-use” flow-condition pressure and temperature
values (FlowPressure and AbsFlowPressure) depending upon the input selection, validity of the
input data, and the selected data source upon alarm in Equation C -10 (see Annex C).
The flow-condition pressure is configurable (via the EnablePressureInput data point) to be:

7. Status information
This section documents the HART primary, secondary, third, and fourth variables for the
Rosemount Ultrasonic Gas Flow Meter.
The meter status information is derived from Boolean database points. For host display
purposes, the status information is divided into three categories:
• Failed - indications that the meter is not working properly and has lost measurement
• Maintenance - indications that the meter requires operator intervention
• Advisory - indications that the meter has information but is still measuring flow and
does not require operator intervention
The meter uses the following mechanisms for communicating the status information to the
host system:
• the Device Status Byte sent with every slave response,
• the Read Additional Device Status Universal Command 48 (see Section 7.2)
• the device-specific command for reading detailed status information Command 140
(see Section 10.1.13).
Device-Specific Command 141 (see Section 10.1.14) is used to acknowledge status Boolean
database points that require acknowledgment.
The database point mapping for the Device Status Byte is shown in Table 7-1. Command 48
database point mapping is shown in Table 7-2. Note that for Command 48, only the first 16
bytes (numbered 0 through 15) shall be sent by the HART Slave. Additional Device Status
information shall be communicated via Device-Specific Command 140 (illustrated in the
command definition in Section 10.1.13).

10.1.1 Command 128 Write analog output configuration
This command is used to configure the meter's specified analog output. The meter provides two
analog outputs: Analog Output 1 (AO1) and Analog Output 2 (AO2). Analog Output 1 supports
both conventional 4-20 mA output and HART output, whereas Analog Output 2 supports only
conventional 4-20 mA output. This command is primarily provided to allow configuration of
Analog Output 2. It can be used to configure Analog Output 1 but the preferred method is to
configure the output via the supported HART Universal and Common commands.
